Extraction method of traffic parameters based on detecting traffic waves at intersections

Extraction of traffic parameters, such as queue length, stop delay and etc, of a road section between intersections is significant for traffic signal control. It is a challenge to get high precision parameters by video processing technologies during peak hours, for the serious vehicle queue. We propose a method of acquiring traffic parameters based on detecting traffic waves at intersections. We use information techniques to fuse the images from two cameras to detect and track traffic waves. On this basis, the various parameters are calculated with high precision. Experimental results show that the method has better performance during different peak periods.
